' GATE Loox. f

` The present invention is directed to improvements in gate locks.

The rprimary objectfotI provide a loclrmore particularly designed toruse in connection with wire strand or 'rameless gates, the constructionbeing such *thaty the-gate can be easily opened or closed,

the lock being ot such construction as to exi ert ktension upon thegate, to hold the same securely in its closed position.

Another object of the invention is to provide a device ot the characterso constructed that when in its locked position the passage of smallanimals through the gate opening is prevented, the construction beingsuch, how ever, that the gate can be held partially open A to permitpassage of small animals or persons when desired.

In the accompanying drawing: I Figure 1 is an elevational view showingthe gate in its locked position. s

Figure 2 is a similar View, showing the gate partially unlocked. l

Figure 3 is a top plan view of Figure 2. Figure 4 is a top plan view ofFigure 1. F igure5 is a sectional view on line 5 5 of Figure 2. f

Figure 6 is. a sectional viewk on line 6 6 ot Figure ,2.

Referring to the drawing, 1 and2 designate the gate posts, and 3 thegate which is formed from a plurality of strands of horizontallydisposed 'cables` 4, having one ot their ends suitably secured to thepost 1. u Ther lock beam 5 is formed from a pair ot I ksections 6 vand7, the section 6 having a longitudinal groove 8 formed upon its innertace and when the sections are secured together by the bolts 9 thegroove is closed by the associated sections, and constitutes a bearing,the purpose of which will later appear. .The cables 4 are securedV tothe lock beam 5 in order that when the gate is, closed the cables willbe'stretched across the gate opening.y Associated with the lock beam 5is a crank `sha-ft 10', the intermediate port-ion of which is journaledin the bearing provided by the groove 6. The lower end of the crankshaft is journaled ina bearing 11 formed in the plate 12 which isembedded in the ground adjacent the gate post, 2 and anchored there Theupper end of the cranls shaft is providedwith a terminal eye theinvention is to 13, which'terminates in'a substantially horizont-allydisposed operating leverlt.

The section 7 of the lock beam is somewhat longerrthan its companionsection, in order that thevextended end thereof will constitute a stop15 for the lever 14 when the gate is closed. V Y

A band 16 is secured to the post 2 in any suitable manner andsubstantially in the same plane `as the eye 13, said band having an eye17 to which is secured one end of the chain 17 the other end ot' whichhas a hook 18 connected thereto. This .hook is capable, when engagedwith the eye 13, to hold the gate securely closed or in a partially openposition.

When the hook 18 is fully engaged from the eye 13 the beam 5 can belifted from the plate 12 and carried to one side of the roadway, thusleaving the gate opening unobstructed to permit the passage of vehiclesand stock.

To securely close the gate thehook 18 is engaged in the eye 13 and asthe lever 14 is swung towards the post 2 the crank shaft 10 will movepast center and exert a tension upon the cables 4 forming4 the gate.

This lever cank continue to swing until the upperv end thereof engagesthe stop 15 and the lever engages the post 0, and at which time thecables are taut.

To open the gate it is only necessary to reverseV this operation. Shouldit be desired to only partly open the gate in orderV to provide a smallpassage between thek beam 5 and post 2, the lever is swung away from thepost, and the alct that the hook is not vdisengaged from the eye thebeam will be sustained inra vertical position, as shown in Figure 1 ofthe drawing. In this manner aV small space is provided to permit aperson to pass through the gate opening withoutV fully opening vthegate. By connecting the hook 18 and plate 12 to the post Y 2 by therespective chains 17 and 12', permit said hook and plate to be adjustedrelative tok post 2 in order to take up slack in the cables 4 of thegate should they stretch.l This is accomplished by simply changing thelink connections between thefposts and the chains 17 "and 12. n

Having thus described the `invent-ion, I claim:

1. Thecombination ywith a gate, of a. post,

a loei beain Carried by the gate and having a stop (thereon, a crankShaft ,ijonrnaled longitudinally in the beam and having its lower endjonrnaled in the roadway, Jfhe npper end oil' said crank shaft having'an operating lever and an eye, a hook carried by [he post fordeiaehablyv engaging' the eye, `eaid lever being4 operable to swingv theupper end oli the crank arin into engagement with the slop and heldengaged therewith hij the tension of the gate.

2. The eolnbinaiiim with a gate and a post, oI a` hooi; Vlexiblji' andadjnsi'ably eenireeted with the posi, a leek bean'i Carried by he gate,Said benin haringl a. crank shaft operatively connected therewith, meansfor detaihably Securing` the hook io the Crunk shaft, said crank shafthaving an operating Lemme lever Capable, when swung in one direction toexert tension simultaneously upon ihe hook and its Connection and gateand to re,- lieve the tension when swung in a reverse direction.

3. The Combination with a gaie and post, of a locking beanl consistingof a pair oil Sections, a crank shaft jonrnaled in the beam and betweenthe seetonev thereof, the crank Shaft liaving an eye i'erniinating in anoperating lever, aV detachable eonneetion between the post and eye, saidlever, when swung in one dil'eeiion exerting tension upon the gaie andeonneei'ion7 ari and vfor the pinpose set forth.
